Final answer:
An EMT would place gloved fingers into the vaginal opening during pregnancy related complications when there is a medical emergency such as a prolapsed umbilical cord or excessive bleeding.
Step-by-step explanation:
An EMT would place gloved fingers into the vaginal opening during pregnancy related complications when there is a medical emergency such as a prolapsed umbilical cord or excessive bleeding. In cases of a prolapsed umbilical cord, the cord slips through the cervix and precedes the baby into the birth canal. The EMT would use their fingers to lift the baby's head off the cord to prevent compression and cut off blood supply.
In cases of excessive bleeding, the EMT may need to manually compress the uterus to control bleeding. This requires inserting gloved fingers into the vaginal opening and applying pressure to the uterus.
It is important to note that these interventions should only be performed by trained medical professionals in emergency situations.
